About pollen in Mission Viejo
Pollen levels in Mission Viejo are quiet today, with weeds standing as the only active source, and even that is at a very low level. Most people should be able to spend time outdoors without noticing any effects, and this is a good stretch for those who are typically sensitive to catch a break. Looking ahead, the next several days should bring more of the same, with weed pollen expected to hold steady at this very low level rather than build toward anything noticeable. This lull fits the season, as tree pollen from local varieties like oak, sycamore, and eucalyptus peaked back in spring and grasses have largely wound down after their late-spring push. Ragweed and other late-summer weeds are the ones to watch as the season progresses, but for now, conditions remain calm across the board.
